Description

The present invention relates to a car wash device with a pure water generator that generates pure water from tap water using a cartridge type ion exchange resin housed in an exchangeable manner and uses the generated pure water to wash vehicles such as automobiles.

Conventionally, it is widely practiced to use tap water for cleaning vehicles such as automobiles.
However, if tap water is used to wash the car, dust adhering to the car body can be removed, but if left washed, minerals such as calcium and magnesium contained in "tap water" will remain on the painted surface when it dries. There was a problem that "water stains", so-called "water spots", remained. Especially when the color of the car body is black, it becomes a very noticeable stain. For this reason, it was necessary to wipe off the water before it dried, which required time and effort to wash the car.

Therefore, by using "pure water" when washing the car, it is possible to keep the water stains on the vehicle body overwhelmingly small. For this reason, "pure water" is mainly used in commercial car wash machines. A pure water generator using an ion exchange resin or a reverse osmosis membrane method is used in a commercial car wash machine.

Patent Document 1 discloses a pure water car washing device that can be conveniently used without lowering the purity of pure water when rinsing pure water on a car body washed with a cleaning agent or water.
That is, the pure water car wash device includes a first car wash unit and a pure water ejection unit, and the pure water ejection unit uses the pure water generator and the pure water housed in the pure water generation unit. It is equipped with a pressurized tank that sends water and an injection nozzle that ejects pure water toward the vehicle body. Then, the injection nozzle is attached to the tip of the horizontal pipe, and the horizontal pipe is extended in a direction orthogonal to the central pipe. The horizontal pipe is a horizontal pipe having a short overhang length to be sprayed onto the upper surface of the vehicle body and a vehicle body. It is formed as a horizontal pipe with a long overhang that sprays on the side surface, and is configured to spray evenly over the entire vehicle body.

In addition, two pure water generation modules are arranged in the pure water generation unit, and the water supplied from the tap water supply port flows in from below the first pure water generation module, while being generated. The pure water flows into the pressurized tank from above the first pure water generation module, while the drainage of the first pure water generation module flows in from above the second pure water generation module. Below the second pure water generation module, on the one hand, the pure water generated by the second pure water generation module flows into the pressurized tank, and on the other hand, the drainage of the second pure water generation module is discharged from the drain port to the outside. It is configured to drain into.
This pure water generation module generates pure water by the reverse osmosis membrane method.

Utility model registration document 2 discloses a technique for a holder of a small ion exchanger for generating pure water or deionized water used at the time of car washing.
That is, the conventional holder is large because it is provided with a mounting table on which the ion exchanger is placed, a wall for fixing the ion exchanger, and a handle attached to the wall. The device described in Document 2 solves the problem that the mounting table can be moved by attaching wheels, but the mounting table is large and difficult to handle.
The holder according to the present invention is connected to a fixing portion fixed to the lid of the ion exchanger, a handle portion attached to the fixing portion, and a connecting portion connected to the fixing portion and extending to the outside of the lid covering portion. It is composed of a pair of legs that bend from the portion and extend along the side surface of the container body.

Further, as a structure of a general pure water generator using a conventional ion exchange resin, for example, the following is known. That is, as shown in FIG. 12, an ion exchange resin 92 is filled in a long cylindrical case 91 called a column to a height of about 8 minutes, and an elongated water collecting pipe 93 is substantially near the bottom surface in the central portion of the case 91. Has been inserted. A raw water inlet 94 and a pure water outlet 95 are arranged to face each other on the upper part of the case 91. The raw water inlet 94 is an inflow port for raw water, and raw water such as tap water flows in in the direction of the arrow. The raw water flowing in from the raw water inlet 94 flows into the ion exchange resin 92, collects water in the case 91, and immerses the ion exchange resin 92.

When the raw water in which the ion exchange resin 92 is immersed passes through the ion exchange resin 92 in the direction of the arrow, the ions in the raw water are exchanged to generate pure water. The pure water generated by the ion exchange resin 92 is collected in the water collecting pipe 93 at the lower part of the case 91, passes through the water collecting pipe 93, and is led out from the pure water outlet 95 to the outside.

As described above, the ion exchange resin 92 makes it easier for the raw water to come into contact with the ion exchange resin 92 by lengthening the channel length of the raw water passing through the ion exchange resin 92, thereby increasing the efficiency of ion exchange. Is configured so that it does not flow out without being ion-exchanged. For this reason, the height of the storage case 91 of the pure water generator using the commercially available ion exchange resin 92 is about several tens of centimeters to 1.3 m. Therefore, it leads to the problem that it is tall and not easy to handle for use in ordinary households.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the drawings are schematic, and the arrangement of each part and the ratio of dimensions do not always match the actual ones.

FIG. 1 is a perspective view showing the configuration of a car wash device 100 with a pure water generator according to the present invention. In this figure, the car wash device 100 with a pure water generator according to the embodiment of the present invention generates pure water from the tap water 21 for supplying tap water which is raw water and the tap water supplied from the tap water 21. It is composed of a pure water generator 1 to be used, a pure water hose 29 for drawing out the pure water generated by the pure water generator 1, and a sprinkler nozzle 4 connected to the end of the pure water hose 29.

The tap water hose 21 supplies tap water, which is raw water, to the pure water generator 1. The tap water hose 21 has its receiving port connected to the tap water faucet 20 and its outlet connected to the joint 22 of the pure water generator 1, and the tap water discharged by twisting the faucet 20 is discharged from the pure water generator 1. Supply to.

The pure water generator 1 generates pure water from tap water supplied via the tap hose 21. The tap water flowed into the generated water case 10 of the pure water generator 1 through the joint 22 in the direction of the arrow, and was arranged in the generated water case 10 via the T-shaped pipe 24 and the communication pipes 25a to 25d. It flows into the ion exchange resin cylinders 14a to 14d. Hereinafter, the arrows in the pipes in the drawings indicate the water flow direction.

The pure water generator 1 houses, for example, four ion exchange resin cylinders 14a to 14d evenly in front, back, left, and right in a substantially rectangular generated water case 10.
In the ion exchange resin cylinders 14a to 14d, the lower part of the cylinder is formed in a tapered shape with a tapered tip, and the upper part of the cylinder is formed flat to form a substantially funnel-shaped cylinder.
Then, an outer cylinder 19 constituting the substantially funnel-shaped exterior and an inner cylinder 18 accommodating the cartridge 17 as a storage body 17'containing the ion exchange resin are formed inside the outer cylinder 19, and the entire body is doubled. It constitutes a cylinder. The inner cylinder 18 generates pure water from tap water by the action of the ion exchange resin when tap water passes through the cartridge 17 containing the ion exchange resin. The details will be described later.

In addition, casters 13 are arranged at the four corners of the lower part of the generated water case 10 so that they can be moved. A cover 12 that opens on one side from the front to the top is arranged above the cover 12, and the cartridge is housed in the inner cylinder 18 of the ion exchange resin cylinders 14a to 14d by opening the cover 12. 17 can be replaced, the switching valve 26 can be opened and closed, and internal maintenance and inspection can be performed.

The switching valve 26 is a valve for switching the generated pure water or the inflowing tap water to the pure water hose 29 by rotating the lever handle 27 by 90 degrees. That is, when the lever handle 27 is set to the "pure water" side, the pure water generated via the ion exchange resin cylinders 14a to 14d, which will be described later, is supplied to the pure water hose 29. When the lever handle 27 is set to the "raw water" side, the inflowing tap water is directly supplied to the pure water hose 29 via the direct pipe 28.
The watering nozzle 4 sprinkles pure water or tap water supplied from the pure water hose 29 to the vehicle 6.

Therefore, when removing the rough dirt of the vehicle 6 to be washed, the lever handle 27 is switched to the "raw water" side to use tap water, and when finishing, the lever handle 27 is switched to the "pure water" side to be pure. It is desirable to use water.

That is, as shown in FIG. 2, the faucet 20 is connected to the receiving port of the water hose 21, and the outlet of the water hose 21 is connected to the receiving port of the joint 22 and introduced into the generated water case 10. The joint 22 is connected to the receiving port of the T-shaped pipe 24.
The T-shaped pipe 24 branches the running water channel. That is, one end of the outlet from which the T-shaped pipe 24 is branched is connected to the receiving port of the communication pipe 25a, and the other end of the branch is connected to the receiving port of the direct pipe 28. The outlet of the connected communication pipe 25a is connected to the water guide hole 15a at the lower end of the ion exchange resin cylinder 14a, and the discharge hole 16a at the lower end of the outer cylinder 19 of the ion exchange resin cylinder 14a is an adjacent next-stage communication pipe. It is connected to the receiving port of 25b, and the outlet of the communication pipe 25b is connected to the water guide hole 15b at the lower end of the inner cylinder 18 of the ion exchange resin cylinder 14b.

Hereinafter, in the same manner, the discharge hole 16b at the lower end of the outer cylinder 19 of the ion exchange resin cylinder 14b is connected to the receiving port of the communication pipe 25c, and the outlet of the communication pipe 25c is the inner cylinder 18 of the ion exchange resin cylinder 14c. It is connected to the water guide hole 15c at the lower end, the discharge hole 16c at the lower end of the outer cylinder 19 of the ion exchange resin cylinder 14c is connected to the receiving port of the communication pipe 25d, and the outlet of the communication pipe 25d is the ion exchange resin cylinder 14d. It is connected to the water guide hole 15d at the lower end of the inner cylinder 18, and the discharge hole 16d at the lower end of the outer cylinder 19 of the ion exchange resin cylinder 14d is connected to one receiving port of the switching valve 26 via the communication pipe 25e. Further, the outlet of the direct pipe 28 is connected to the other receiving port of the switching valve 26.

Further, the outlet of the switching valve 26 is connected to the joint 23, the outlet of the joint 23 is connected to the pure water hose 29, and the watering nozzle 4 is connected to the end of the pure water hose 29.

Since the flow channel is formed by the above piping connections, as shown in FIG. 2, the four ion exchange resin cylinders 14a to 14d communicate with each other to form one flow channel. ..

Then, when the lever handle 27 of the switching valve 26 is switched to the "pure water" side, the faucet 20 at the start of running water to the watering nozzle 4 at the end communicate with each other via four ion exchange resin cylinders 14a to 14d. , Form a single water channel. Therefore, when the faucet 20 is twisted, tap water flows into the ion exchange resin cylinders 14a to 14d arranged in the generated water case 10 via the water hose 21, and the inner cylinders of the ion exchange resin cylinders 14a to 14d. Pure water is generated in the water 18 and the generated pure water is supplied to the watering nozzle 4 via the pure water hose 29 and sprinkled on the vehicle 6 by the watering nozzle 4.

When the lever handle 27 of the switching valve 26 is switched to the "raw water" side, the faucet 20 at the start of the running water and the watering nozzle 4 at the end communicate with each other via the direct pipe 28 to form a single flowing channel. Therefore, when the faucet 20 is twisted, tap water passes through the direct pipe 28 arranged in the generated water case 10 via the water hose 21, is supplied to the watering nozzle 4 via the pure water hose 29, and is supplied to the watering nozzle 4. Water is sprinkled on the vehicle 6 as it is.

The water quality sensor 31 is provided in the outlet pipe of the switching valve 26 and is connected to the water quality meter 3. The water quality meter 3 receives a signal from the water quality sensor 31, measures the conductivity of pure water or tap water in the water quality measurement circuit 32, and displays the water quality state as the measurement result on the display 33. The display 33 is composed of a liquid crystal display (LCD) or a light emitting diode (LED), and the measurement result is a digital number, an analog bar, or a light emitting diode for each color such as normal (green) caution (yellow) abnormality (red). Display is performed using LED). As a result, the quality of pure water or tap water can be known. For example, when the yellow lamp lights up, it is possible to know that it is time to replace the cartridge 17, so that the cartridge 17 can be purchased or ordered. Can be taken.

The water quality meter 3 uses the battery 34 as a drive power source. That is, since the power consumption of the circuit of the water quality meter 3 can be configured to be extremely small, for example, when a commercially available 9V square battery (006P type alkaline battery) is used, it is possible to wash about 400 vehicles 6. , Tested and confirmed. In addition, by making the water quality meter 3 battery-powerable, it is not necessary to take power from an outlet, power cordlessness is realized, and a wide range of movement is possible without being restricted by the movable range due to the length of the power cord. ..

Next, a configuration in which tap water flows into each of the ion exchange resin cylinders 14a to 14d will be described. Here, the ion exchange resin is a kind of synthetic resin and has a structure in which a part of the molecular structure is ionized as an ion exchange group, and when removing the ions contained in the raw water, the ions possessed by itself are used in the raw water. It is an ion exchanger formed of a porous synthetic resin having the property of exchanging with other ions existing in the raw water instead. Therefore, if all the ions of the ion exchange resin are exchanged with the ions of the raw water, pure water can no longer be generated, and the ion exchange resin needs to be exchanged. The shape of the ion exchange resin is generally formed in the form of particles having a diameter of less than 1 mm.

The cartridge 17 is a water-permeable container for storing the ion exchange resin. The ion exchange resin cylinders 14a to 14d accommodate the cartridge 17 containing the ion exchange resin inside the inner cylinder 18, and use the ion exchange function to generate pure water from the inflowing tap water.

Further, the cartridge 17 has a replaceable structure. For example, the outer cylinders 19 of the ion exchange resin cylinders 14a to 14d have male screws screwed on the outer peripheral surface of the upper end, and the upper lid 55 has female screws screwed on the inner peripheral surface of the lid via the packing 56. It is configured so that it can be screwed. Then, with the faucet 20 closed, the cover 12 is opened, the upper lid 55 on the upper part of the ion exchange resin cylinders 14a to 14d is turned to the left to remove it, and the cartridge 17 is taken out from the inner cylinder 18. Then, a substitute cartridge 17 is accommodated, and the removed upper lid 55 is turned to the right to cover the cover 12 so as to close the cover 12. In this case, the upper lid 55 may be provided with a handle so that it can be turned. Of course, the upper lid 55 can also have a screwed structure.

The ion exchange resin cylinders 14a to 14d used in the car wash apparatus with a pure water generator according to the present invention keep the height as low as about 300 mm, and secure the water channel length by connecting four in series. Therefore, it is possible to generate pure water.

For this purpose, as described above, the ion exchange resin cylinders 14a to 14d are formed in a tapered shape with a tapered tip at the lower portion of the cylinder, and the upper portion of the cylinder is formed flat to form a substantially funnel-shaped cylinder. There is.
An outer cylinder 19 forming the substantially funnel-shaped exterior and an inner cylinder 18 are formed inside the outer cylinder 19 to form a double cylinder as a whole. Water guide holes 15a to 15d are formed at the lower ends of the inner cylinders 18 of the ion exchange resin cylinders 14a to 14d, and the outer cylinder 19 forms a hollow cylindrical water passage that surrounds the outer circumference of the inner cylinders 18 at the lower ends. Is formed with discharge holes 16a to 16d. The discharge holes 16a to 16d are connected in series with the water guide holes 15a to 15d formed at the lower ends of the inner cylinders 18 of the adjacent ion exchange resin cylinders 14a to 14d, respectively, by communication pipes 25a to 25d. Has been done.

Flowing water flows into the inner cylinders 18 of the ion exchange resin cylinders 14a to 14d connected to the communication pipes 25a to 25d through the water guide holes 15a to 15d.
The flowing water flowing from the water guide holes 15a to 15d overflows from the upper part of the inner cylinder 18 to the outer cylinder 19 through the cartridge 17 containing the ion exchange resin housed in the inner cylinder 18. The overflow flows from the discharge holes 16a to 16d formed at the lower end of the outer cylinder 19 via the water flow passage surrounding the outer circumference of the inner cylinder 18 formed in the outer cylinder 19 and via the communication pipes 25a to 25d. , It flows into the adjacent ion exchange resin cylinders 14a to 14d in the next stage.

The reason why the tap water flows in from the water guide hole 15a formed at the lower end of the ion exchange resin cylinder 14a is because the height of the ion exchange resin cylinders 14a to d is as low as about 300 mm. If it flows in from above, bubbles are generated during running water, and they remain as bubble pools in the running channel, making it impossible to secure sufficient time for the running water to come into contact with the ion exchange resin, resulting in pressure loss. This is to prevent it from occurring or the flow velocity from becoming unstable.

That is, as shown in FIGS. 2 and 3, the ion exchange resin cylinders 14a to 14d have the lower portion of the cylinder formed into a tapered shape with a tapered tip. By forming in this way, as shown by the arrow in FIG. 3, the water flow at the connecting portion with the communication pipes 25a to 25d becomes smooth, and bubble accumulation is less likely to occur.

Further, the ion exchange resin cylinders 14a to 14d are provided with a water diffusion mechanism portion 5 below the ion exchange resin cylinders 14a to 14d, which divides and diffuses the flowing water from the water guide holes 15a to 15d.

Water diffusion mechanism section 5 is tap water through the water guide holes 15a~15d flowing into the inner cylinder 18 of the ion exchange resin cylinder 14a~14d hits the baffle plate 51 of the water diffusion mechanism section 5, tap water By temporarily blocking the momentum of the water flow, the flow velocity is reduced and the flow velocity is made uniform.

That is, when the water diffusion mechanism portion 5 is not provided, the ion exchange resin cylinders 14a to 14d pass through the water supply holes 15a to 15d as shown in the explanatory diagram of the water flow in the vicinity of the water supply holes 15a to 15d in FIG. The tap water flowing into the inner cylinder 18 has a large flow velocity in the central portion of the running water and a small flow velocity in the peripheral portion, so that the flow velocity of the tap water is not uniform. Therefore, the running water directly hits the central portion of the bottom surface of the cartridge 17 containing the ion exchange resin at a large flow velocity, and flows into the next stage ion exchange resin cylinders 14b to 14d without sufficient ion exchange by the ion exchange resin. This causes a problem that the purity of pure water does not improve.

The water diffusion mechanism portion 5 is for solving such a problem, and as shown in FIGS. 5 and 6, a substantially funnel-shaped lower cover formed under the ion exchange resin cylinders 14a to 14d. 53, a substantially disk-shaped jam plate 51 arranged in the upper space of the water guide holes 15a to 15d, and a cross plate erected in the circular opening edge of the lower cover 53, and the jam plate at the center where the cross characters intersect. It is composed of a support 52 provided with a 51.
A diffusion chamber 54 for running water is formed.

Since the obstruction plate 51 is arranged in the water diffusion mechanism portion 5 as described above, the tap water flowing in from the water guide holes 15a to 15d is ejected upward as shown in FIG. It directly collides with the baffle plate 51, and diverges and diffuses radially in the horizontal direction around the baffle plate 51.

The separated tap water flows toward the inner wall surface of the inner cylinders 18 of the ion exchange resin cylinders 14a to 14d, and then flows upward. Further, at the peripheral end portion of the baffle plate 51, a vortex flowing into the upper part and the lower part of the baffle plate is generated, and after passing through the vortex, flows upward and diffuses.

Therefore, as shown in FIG. 7, the tap water flowing in from the headrace holes 15a to 15d is ejected upward and directly collides with the baffle plate 51, where the tap water is decelerated and slowed down. Further, the flowing water that collides with the hindrance plate 51 and is shunted radially in the horizontal direction flows in the direction of the inner wall surface of the inner cylinder 18, and then flows upward, or flows upward after passing through a vortex.
Therefore, the water flow distribution when the cartridge 17 is not housed in the inner cylinder 18 is as shown in the flow velocity distribution diagram of the water flow in the vicinity of the water guide holes 15a to 15d in FIG. It is possible to achieve a uniform flow velocity. In the figure, the flow velocity decreases in the order of vertical stripes, diagonal stripes, horizontal stripes, dotted diagonal stripes, and plain stripes.

The running water whose speed has been reduced and the flow velocity has been substantially made uniform in this way is uniformly contacted over time while stirring the ion exchange resin stored in the cartridge 17 in the inner cylinder 18 by diffusion due to diversion or eddy current. However, since it passes through, ion exchange in raw water can be made efficient, and pure water can be reliably generated.

Next, another embodiment of the water diffusion mechanism unit 5 will be described with reference to FIGS. 9 to 11.
As shown in FIG. 9, the water diffusion mechanism portion 5 includes a substantially funnel-shaped lower cover 53 formed under the ion exchange resin cylinders 14a to 14d constituting the container, and the water diffusion mechanism portion 5.
A substantially disk-shaped obstruction plate 51 arranged in the upper space of the water guide holes 15a to 15d and a cross-section erected in the circular opening edge of the lower cover 53, and the obstruction plate 51 is provided at the center where the cross-sections intersect. It is also composed of a support column 52 having an inclined cross section. Therefore, the flowing water flowing in from the water guide holes 15a to 15d collides with the baffle plate 51 and is shunted radially in the horizontal direction, and a part of the flowing water also collides with the plurality of columns 52.

Another embodiment of the water diffusion mechanism unit 5 according to the present invention is intended to change the direction of the water flow colliding with the plurality of columns 52 to perform commutation. That is, as shown in FIG. 9, the support column 52 is formed by inclining the cross section to change the direction of flowing water.

Specifically, when the cross section of the support column 52 is formed as shown in FIG. 10A, the flowing water that collides with the support column 52 is evenly divided and diffused radially in the horizontal direction.
As shown in FIG. 10B, another embodiment of the water diffusion mechanism portion 5 according to the present invention is configured to change the direction of flowing water by forming the support column 52 with an inclined cross section. Further, this inclination is also formed so as to be connected to the baffle plate 51. Therefore, as shown in FIG. 10C, the flowing water colliding with the support column 52 is commutated at an angle of reflection angle θ with respect to the incident angle θ.

As shown in the plan view of FIG. 11, the flowing water that collides with the support column 52 and is commutated forms a spiral flow that swirls in the arrow direction in the inner cylinder 18 of the ion exchange resin cylinders 14a to 14d and diffuses. To do. That is, the flowing water that collided with the disturbing plate 51 and the support column 52 is commutated and rises in a spiral shape while swirling in the inner cylinders 18 of the ion exchange resin cylinders 14a to 14d, and the ions stored in the cartridge 17 While stirring the exchange resin, the resin is evenly contacted and passed through over a long period of time, so that ion exchange in the raw water can be made more efficient and pure water can be reliably produced.

Since the car wash device 100 with a pure water generator according to the present invention is configured as described above, pure water can be generated and sprinkled by using the pressure of tap water, and the power of a pump or the like can be used. It has an effect that makes it unnecessary.
In addition, while conventional products take power power such as pumps from an outlet, the present invention realizes power cordlessness because it does not have power, and can move over a wide range without being restricted by the length of the power cord. It has the effect that makes it possible.
Further, although deterioration of the insulation of the power supply system is prohibited around water, since the present invention does not require an outlet power supply, there is no need to worry about the occurrence of an electric shock accident due to deterioration of the insulation of the power supply system.

Further, in the pure water generator 1, four ion exchange resin cylinders 14a to 14d are housed and arranged evenly in the front, back, left and right in the generated water case 10, so that the height is lowered while ensuring the water channel length. By providing the casters 13 with the lower four corners of the pure water generator 1 protruding, the effect of being stable, being hard to fall down, and being easy to move can be obtained.

Further, by forming the peripheral end of the connecting portion between the communicating pipes 25a to 25d, the ion exchange resin cylinders 14a to 14d and the water guiding holes 15a to 15d in the generated water case 10 in a tapered shape, the communicating pipes 25a to 25d can be connected to each other. Since the water flow at the connecting portion becomes smooth, the effect of suppressing the generation of air pools is achieved.

Further, since the water diffusion mechanism unit 5 is configured as described above, it is possible to reduce the speed and homogenization of the water flow flowing into the inner cylinders 18 of the ion exchange resin cylinders 14a to 14d. , It has the effect of making ion exchange efficient.

Further, since the rectifying plate is configured so that the flowing water flowing in from the water guide holes 15a to 15d collides with the obstruction plate 51 and is radially divergently distributed and diffused, the rectifying plate is arranged above the water guide holes 15a to 15d. It is possible to prevent running water from directly hitting the bottom surface of the cartridge 17 containing the ion exchange resin housed in the inner cylinders 18 of the provided ion exchange resin cylinders 14a to 14d, and the ion exchange resin cylinders 14a to 14d. Since it is possible to reduce the speed and homogenization of the water flow flowing into the inner cylinder 18 of the above, it is possible to achieve the effect of efficiently exchanging ions.

Further, since the plurality of columns 52 supporting the disturbing plate 51 are arranged at a predetermined angle with respect to the horizontal plane and form a plurality of spiral rectifying plates as a whole, the water guide holes 15a to 15d When the flowing water flowing in from the hindrance plate 51 and the support column 52 collides with each other, the flowing water is commutated at a predetermined angle to form a spiral flow swirling in that direction and diffuses. Therefore, it is possible to reduce the speed and homogenization of the water flow flowing into the inner cylinders 18 of the ion exchange resin cylinders 14a to 14d.
That is, the running water spirally rises while swirling in the inner cylinders 18 of the ion exchange resin cylinders 14a to 14d, and takes time evenly as a whole while stirring the ion exchange resin stored in the cartridge 17. Since they come into contact with each other and pass through, the ion exchange in the raw water can be made more efficient, and the effect of reliably producing pure water is achieved.

Further, although the shape of the obstruction plate 51 has been described as being disk-shaped, the shape of the obstruction plate 51 may be, for example, a triangle or a quadrangle as long as it has a shape that can block the flow of water flowing from the water guide holes 15a to 15d and cause commutation. There is no problem, and it is not limited to a disk shape. Further, the height, position, and size are not limited to those described in the present specification or drawings.

Further, although the support column 52 has been described as having an elongated rod shape in FIGS. 5, 6, 9 and 10, it does not matter if it has a shape capable of slowing down the running water and changing the direction of the running water, and has a width and a thickness. Is not limited to such a shape. For example, it may be wide, fan-shaped, or have a curved cross section to bend the direction of running water.
